People absolutely DID want them. Thats the point.
It used to be, proxy was simply not permitted, and the 'best' magic was competitive, tournament magic, in person.
That meant, if you wanted to play a certain deck, you had to own the real cards, that were as scarce as Wizards wanted.
Supply, Demand, Artificial Scarcity, and perceived value, were all very real in terms of the secondary market. I had cards go from $60 per, to $6, over night due to a combination of reprint, deck competitiveness (aka demand) and the general decline of competitive in person play.
I dont even want to look at the remaining handful of cards I have left, to see the 'value' they have retained.
